Abstract: We present a model of credit cycles based on a new psychological formulation of the expectations mechanism. Agents form “stereotypical” expectations whereby they over-weight, in their belief revisions, the future outcomes that have become more likely in light of incoming data. This model of context dependent beliefs is based on a formalization of Kahneman and Tversky’s representativeness heuristic that has been previously used to explain a substantial amount of experimental evidence in psychology as well as the social phenomenon of stereotyping. Beliefs in this formulation are forward looking, immune to the Lucas critique, and contain rational expectations as a special case. Beliefs exhibit excess volatility, over-reaction to news, and systematic reversals. These dynamics account for many recently documented features of credit cycles and macroeconomic volatility without resort to financial frictions. In particular, they generate systematic reversion of a financial boom into a bust in the absence of deteriorating fundamentals.

PhD and former MA in Applied Economics students will present six of the applied projects they worked on this year.

• Policy uncertainty is difficult to measure. This project finds a way by exploring media coverage. 
• How successful are second-generation immigrants? This project explores their success in the U.S. labor market. 
• Public spaces affect quality of living. In this project, real estate prices are used as a proxy to quantify this effect. 
• Is it economically viable to remodel the Negrelli viadukt in Karlin and turn it into a creative incubator? 
• Are kids from differently educated families given the same chance for a better future? This project studies the connections between parental education and children’s attendance of kindergarten. 
• Current monetary policy is in an unusual situation, as interest rates are at the zero-lower bound. What are the implications?
